According to Lt. Bill Davis with the Bossier Parish Sheriff's office 26-year old Christopher Kerr used his position as substitute teacher and sports umpire to gain access to children. It is alleged that Kerr used these opportunities to send and request nude photographs. Lt. Davis told the Louisiana Radio Network,

We have at least 30 photos of other girls who are nude or partially nude, who could be in range, it looks like, appearing to about 11-years of age who are victims we have unidentified.

Lt. Davis says he expects more victims to come forward as the investigation of Kerr continues. Kerr is being held in the Bossier Parish Jail on charges of producing and possession of child pornography as well as carnal knowledge of a juvenile. Authorities have identified at least four victims aged 13-16 the Kerr either exchanged photos with or engaged in sexual relations with over the last three years.
